Water (γ = 62.4 lbf/ft^3) flows through a horizontal constant diameter pipe with a cross-sectional area of 8 in^2. the velocity in the pipe is 15 ft /s, and the water discharges to the atmosphere. the head loss between the pipe joint and the end of the pipe is 3ft. find the magnitude and direction of the force on the joint to hold the pipe. the pipe is mounted on frictionless rollers. assume α = 1.0 at all locations.
